Linux - N00b tips!

This would be a good place to find simple & strange little tips for solving problems that tend to trip up new Linux users...

Files that don't exist

If you see "cannot stat 'randomfilename' That generally means the file doesn't exist.

Permission Frustrations

Unlike some other OSs, Linux is fairly consistant with permissions. But a lot of new users are easily confused by what required "root" access.

In general, pretty much any time you see "Permission denied", you can bypass it by adding "sudo" to the start of your command line, then providing your password.

BUT... stop & think about what you're trying to do first!

Personalising Configurations

PATH addition to allow your own scripts & programs to run

Sometimes, you'll want to have some executable stuff of your very own. These things don't need to be accessible to all users on the machine. But, it's be nice to be able to run them without specifying the complete path...

Create a bin directory in your home directory:

• mkdir ~/bin

Then edit your .bashrc file:

• vim ~/.bashrc

and add the following line:

• export PATH="$HOME/bin:$PATH"

(you can activate this change immediately by:

• source .bashrc

)

Place your scripts & executables in this directory & you can now execute them as if they were regular system executables.

Visually Improving the Terminal

• Changing the colours in bash
